Which two statements correctly describe best practices for sizing a firewall deployment with decryption enabled? (Choose two.)

Question

Options

• ASSL decryption traffic amounts vary from network to network.
• BLarge average transaction sizes consume more processing power to decrypt.
• CPerfect Forward Secrecy (PFS) ephemeral key exchange algorithms such as Diffie-Hellman
• DRivest-Shamir-Adleman (RSA) certificate authentication method (not the RSA key exchange

• A
  63% (24)
• B
  13% (5)
• D
  24% (9)

Explanation

When planning a firewall deployment with SSL/TLS decryption enabled, it is crucial to consider the additional processing overhead introduced by decrypting and inspecting encrypted traffic. Here are the details for each statement: SSL decryption traffic varies depending on the organization's specific network environment, user behavior, and applications. For example, networks with heavy web traffic, cloud applications, or encrypted VoIP traffic will have more SSL/TLS decryption processing requirements. This variability means each deployment must be properly assessed and sized accordingly. Ephemeral (DHE) and Elliptic-Curve Diffie-Hellman Exchange (ECDHE) consume more processing resources than Rivest-Shamir-Adleman (RSA) algorithms" (Correct Answer C)? PFS algorithms like DHE and ECDHE generate unique session keys for each connection, ensuring better security but requiring significantly more processing power compared to RSA key exchange. When decryption is enabled, firewalls must handle these computationally expensive operations for every encrypted session, impacting performance and sizing requirements.
